With this device, you can measure square objects, round objects, straight lines, and curved surfaces with ease. **Additional Instructions & Photos here: (Take a sec to vote for this project too!) https://bit.ly/2uBcJPj** This tool is perfect for measuring curved lines or oddly shaped surfaces that are difficult to measure directly with a straight ruler or tape measure. The roller ruler uses a wheel of known dimensions, regularly spaced tick marks, and a counter mechanism to measure up to 1/2 meter in 5 mm increments. -The device is incredibly portable, allowing you to carry an infinitely long ruler wherever you go! It's a simple yet handy tool for homeowners, architects, engineers, interior designers, fashion designers, decorators, art students, or anyone who needs to precisely measure irregularly shaped things on a regular basis. -A note on technical names: The intermittent Geneva drive mechanism is also known as a 'maltese cross drive'. Technically, this device should be called a 'curvimeter', 'opisometer', or 'meilograph'.
